You may need a watch tool to take the links out. If that's not an option, you could try using another pin and ball-peen hammer? Maybe tap the pin halfway, and pull it out with pliers. The pins can bend upon re-inserting them. Upon further review, maybe bring it into the nearest O Store/Vault or jeweler. hahah
Thanks for the reply. I guess I should take it to the local jeweler since I don't have an O store within 90 miles. The only thing that sucks is they charge $16 for watch adjustments...boooo.
There are also 10-15 piece watchmaker kits for $25 or so on eBay. They're not especially high quality (pretty cheap, actually) but they're good enough for those interested in changing their own links or doing some minor work on a timepiece.
